n code, potential unlocked: yet another useless technology offering more stiffness and power with less weight. When will racket manufacturers start hyping features that we really need - like more flexible, less power and more weight? How about making a racket that is heavy, flexible with medium power? I'd try that. Or maybe some useful features like a durable bumper guard or a bumper guard you can replace without replacing the gromments? How about a technology where you can easily adjust the weighting and balance? Or a really useful technology that would allow you to adjust the string tension?
